Actor Jared Leto is in London for the premiere of Dallas Buyers Club, and paid a promotional visit to BBC Radio One in London, England earlier today (January 29, 2014).

At one point Leto have a thumbs up to the throng of fans that greeted him outside the studio.

Leto is in the running for the Best Supporting Actor prize and he admits the acclaim he is receiving for the role proves he was right to end his film hiatus for the project.

In an interview on UK station BBC Radio 1, he said: ”It took six years for this to come to me. I wasn’t looking to make a film but I ended up reading the script and fell in love (with it). I don’t want to sound like a jerk right now but someone told me yesterday that I’ve won over 30 awards for it already. I didn’t even know there were 30 awards to win. The big ones were the Golden Globes and the SAG Awards recently.”

Referring to his Oscar nomination, he added: ”I feel like this is insane and amazing – I feel like the luckiest person in the world. It’s a really special story and I feel proud to be a part of it.”

If you’ve seen the film, then you’ll know that all the praise and recognition for the role that Jared has received is very well deserved.

UPDATE 8:42 P.M. PST:Matthew McConaughey took to social media Saturday to officially announce to his fans the gender and name of his newborn: “Camila (@iamcamilaalves) gave birth to our third child yesterday morning. Our son, Livingston Alves McConaughey was born at 7:43am on 12.28.12,” he wrote on his Whosay page. “He greeted the world at 9lbs. and 21 inches. Bless up and thank you for your well wishes. Happy New year, and just keep livin, Camila and Matthew McConaughey.”

Celebuzz previously reported Matthew McConaughey’s stunning 50-pound weight loss and now his co-star, Hollywood hunk Jared Leto, is slimming down dramatically for his role as a transsexual woman in the film based on the life of Ron Woodroof, a Texas electrician who was diagnosed with AIDS in 1986 .

Photographer Terry Richardson posted pictures of the 30 Seconds from Mars frontman looking extremely gaunt on his blog and Twitter feed — and the 40-year-old even reveals to Vulture magazine he hasn’t eaten in a month!

“Your body goes through weird stages,” Leto said in the interview. “Sometimes it’s hard to hold on to water. But for me, it’s not about the most weight I can lose, it’s more to represent the character.”

According to The Hollywood Reporter, Leto will play “a flamboyant cross-dresser with HIV who helps Woodruff.” And this isn’t the first time the actor has taken extreme measures to transform his weight for his on-screen persona. In 2007, the self-professed vegan, gained 62 pounds to play the infamous murderer of John Lennon in the flick, Chapter 27 — and it came with dramatic consequences. Leto lost the weight so abruptly he was diagnosed with gout.

A barely recognizable McConaughey has sent shockwaves through Hollywood over the last few months since he’s shown the world his drastically thinner frame and revealed to HitFix right before filming began that he weighed 143 pounds, and that is where he would stay. In the interview, he revealed he has “35 percent less energy,” but that he “feels good.”

How did he lose the double-digit weight? McConaughey attributed it to cardio, but “90 percent is based on diet.” His diet has consisted of tea and a little protein.

But the actor, who’s known for his buff physique, is craving junk food. So what is the first thing he wants? A cheeseburger!

“As much as I want a cheeseburger on that day, I think it’ll be damn hard to eat it,” he confessed.

The actor-musician stepped out in full drag on the New Orleans, La., set of The Dallas Buyers Club — a drama chronicling the real life of Ron Woodruff, a heterosexual HIV-positive drug addict who smuggled much-needed medication into the country in 1980s.

With a wig and full face of makeup, a skinny Leto donned a mini skirt and fur coat to transform into his character Rayon, a cross-dresser battling AIDS.

Before slipping into his lady getup on set, the 30 Seconds to Mars frontman prepped by saying goodbye to his body hair. “I just waxed my legs for this new role. Ladies, I feel your pain,” he tweeted, later adding: “What I have learned today: Beauty Is Pain #waxonwaxoff.”

Leto isn’t the only cast member transforming his physique all in the name of art. Matthew McConaughey — who stars as Woodruff — dedicated months to dropping weight, sticking to a restricted high-protein, low-carb diet ahead of filming. “I’m playing a guy who was sick and would have loved to have been healthier but wasn’t,” the actor told Us Weeklyin August. Shedding pounds is “more of a mental thing than a physical thing” he explained. “I’ll get down to the weight I need to get to. I’m on my way, and it’s what I need to do for the job.”

As production began on The Dallas Buyers Club last week, a skeletal McConaughey was almost unrecognizable, sporting a Burt Reynolds-like mustache, longer locks and a dark lesion on his forward, a telltale sign of AIDS affliction.
